Which sentence is grammatically correct?
Do you can help me check the issue?
Modal verbs like can and could do not use do or does in questions.
You can help me check the issue?
Questions with modal verbs should invert the subject and verb: Can you help me?, not You can help me?.
Could you help me check the issue?
Can helping me check the issue?
After can, use the base verb (help), not the -ing form (helping).

In questions, modal verbs like can, could, and should come before the subject. The verb that follows must be in its base form. That's why you say Could you help? instead of Do you can help? or Can helping?
For example, in Should we report this issue? and Might he know the password? The modal verb comes first, and the main verb stays in its base form.
Using do or does with a modal verb is incorrect. You don't say Do you can reset the system? Instead, say Can you reset the system?
Word order is important in English questions. Saying You can help me? sounds unnatural because the subject and the modal verb are not in the right order. The correct form is Can you help me?
